Testicular cancer is the most common solid malignancy in people with testicles aged 15-44 years, accounting for 1-2% of all tumours in males of all ages. Approximately 95% of testicular cancers are testicular germ cell tumours. This Seminar focuses on testicular cancer, with an emphasis on testicular germ cell tumours. We delve into the epidemiology, clinical presentation, disease management, controversies, clinical dilemmas, follow-up, and future directions. Furthermore, we explore distinct treatment approaches for seminoma and non-seminoma testicular germ cell tumours across all clinical stages and discuss post-treatment salvage options after relapse. Our Seminar aims to provide a comprehensive review of testicular cancer, to enhance understanding, and inform clinicians and researchers about the latest developments in management.

In recent years, growing evidence indicates that the nervous system plays an indispensable role in tumor development and metastasis. Elucidating crosstalk between the nervous system and tumor progression has thrived as a hot topic and a new direction for understanding cancer pathogenesis. Notably, many novel discoveries have suggested that neurotransmitter receptors (NRs) are not only widely expressed in cancer cells, but also play key roles in regulating cancer initiation and progression by diverse approaches. In this review, we summarized the latest advance in cancer neuroscience, especially emphasizing the important roles of different NRs in cancer development and prevention. The exemplary studies presented herein illustrate the emerging view that NRs are profoundly influential, manifested in tumor growth, apoptosis, angiogenesis, metastasis, resistance to drugs, and participate in the formation of neural-cancer interactions. In addition, NRs also regulate cellular metabolic processes and tumor microenvironment (TME) remodeling. More importantly, numerous basic and clinical studies have suggested that NRs may be potential targets for cancer treatments, and corresponding agonists or antagonists have been identified effectively in controlling tumor growth and metastasis. In conclusion, NRs are emerging as novel targets for anti-cancer drug exploration and clinical cancer treatments, while trying to uncover deeper mechanisms and connections between NRs and cancer is of high clinical significance and translational value.

IMPORTANCE: Robotic surgery for rectal cancer is widely used, but data on long-term oncological outcomes are still lacking.

BACKGROUND: Childhood obesity is a worldwide public health problem that increases the risk of chronic diseases. In 2016, more than 340 million children and adolescents aged 5 to 19 years were living with overweight or obesity.

This Review offers an evaluation of current treatments for symptomatic uterine fibroids, including uterine artery embolisation, MRI-guided high-intensity focused ultrasound, laparoscopic radiofrequency ablation, transcervical radiofrequency ablation, ulipristal acetate, and oral gonadotropin-releasing hormone antagonists with add-back therapy. Placing these therapies within the IDEAL (Idea, Development, Exploration, Assessment, And Long-Term Follow-Up) framework and the clinical phases of drug development framework, we highlight key gaps in the evidence such as the lack of head-to-head comparisons with standard care, scarce long-term data, and inadequate consideration of real-world fibroid and patient characteristics. We provide a clear overview, assess the strength of the available evidence, and propose a practical flowchart to help clinicians navigate treatment decisions, ensuring the best care for women with symptomatic fibroids at various stages of therapy development. Insight into these matters equips both patient and clinician with essential information to support the process of shared and fully informed decision making. Importantly, this Review also identifies knowledge gaps that contribute to the specification of the fibroid research agenda.

BACKGROUND: The epidemic of overweight and obesity affects more than 390 million children and adolescents aged 5 to 19 years and 37 million children under five years of age. Overweight and obesity are associated with both short- and long-term consequences, including chronic inflammation, metabolic diseases, as well as alterations in the gut microbiome composition. Gut microbiome-based approaches may impact microbiome-related metrics such as diversity or the abundance of intestinal bacteria, which may be linked to obesity-related outcomes. However, evidence regarding the effect of gut microbiome-based interventions for the management of obesity is limited.

CONCLUSIONS: This study presents initial findings on the prevalence of chronic diarrhea among residents of Chinese communities while offering substantiated evidence regarding the significant association between obesity and chronic diarrhea. These findings offer a novel perspective on gastrointestinal health management.

Colorectal cancer (CRC), a major global health concern, necessitates innovative treatments. Chimeric antigen receptor (CAR) T cells have shown promises, yet they grapple with challenges. The spotlight pivots to the rising heroes: CAR natural killer (NK) cells, offering advantages such as higher safety profiles, cost-effectiveness, and efficacy against solid tumors. Nevertheless, the specific mechanisms underlying CAR NK cell trafficking and their interplay within the complex tumor microenvironment require further in-depth exploration. Herein, we provide insights into the design and engineering of CAR NK cells, antigen targets in CRC, and success in overcoming resistance mechanisms with an emphasis on the potential for clinical trials.

IMPORTANCE: Sildenafil citrate may increase uteroplacental blood flow. Its ability to reduce perinatal complications related to fetal hypoxia during labor is uncertain.

CONCLUSIONS: Approximately one-fifth of patients with ischemic stroke had severe neurological deficits on admission. Clinical worsening mainly occurred in the first 3 to 4 days after stroke onset, with brain edema as the leading cause of worsening. Reperfusion reduced the risk of clinical worsening and improved functional outcomes.

CONCLUSIONS: A comprehensive meta-analysis of KM-based IPD enabled the identification of unique miRNA panels predicting the incidence and severity of HFrEF and HFpEF, supporting the clinical usefulness of miRNA profiling for tailored healthcare and risk stratification in HF patients. Nonetheless, more rigorously designed longitudinal studies are needed to validate the clinical application of miRNAs as prognostic and predictive biomarkers.

Definitive treatment of lung cancer with radiotherapy is challenging, as respiratory motion and anatomical changes can increase the risk of severe off-target effects during radiotherapy. Online adaptive radiotherapy (ART) is an evolving approach that enables timely modification of a treatment plan during the interfraction of radiotherapy, in response to physiologic or anatomic variations, aiming to improve the dose distribution for precise targeting and delivery in lung cancer patients. The effectiveness of online ART depends on the seamless integration of multiple components: sufficient quality of linear accelerator-integrated imaging guidance, deformable image registration, automatic recontouring, and efficient quality assurance and workflow. This review summarizes the present status of online ART for lung cancer, including key technologies, as well as the challenges and areas of active research in this field.

IMPORTANCE: Nearly 100 000 children experience physical abuse each year in the US. Among approximately 2000 annual deaths related to child maltreatment, more than 40% resulted from physical abuse, and half of those children were younger than 1 year. Many of these young children had unidentified abusive injuries before the fatal event.
